Q

MK 38 Mod 2 Modes of Operation

A

Surveillance Mode- Weapon station is stationary and only the on mount EOS is driven.
Engagement Mode- Main operational mode, used for initiating fire upon acquired targets. In ENG mode the gun follows the EOS LOS.
Service Operation Mode- Designed primarily for maintenance procedures, but can be used as a backup operational mode in the event of failure in the stabilization circuits.
Manual Operation Mode- Emergency backup mode to be used in the event of total failure in the drive system. Disengages the drive system and control is given to a local operator at the turret itself.

Q

MK 38 Mod 2 Safety Features - Sector Limits

A

Software- Compares the readings of the resolvers against the defined sectors and does not allow firing or motion outside of fire sectors. This is considered a “Soft Stop.”
Electrical- Proximity switches (traverse only). When activated, the switches shift the system to Surveillance mode and disable fire. Firing/Engagement mode is enabled only after manually returning gun to the firing sector.
Mechanical- Mechanical stoppers are positioned to prevent the gun from exceeding the limits which endanger personnel or equipment on the ship.

Q

Close-In Weapon System (CIWS) Firing Breaks

A

Clearing sector hold-back tool – mechanical safety designed to physically keep rounds from being chambered inside the gun. With tool installed, rounds will only cycle in the clearing path of the gun.
Fire Circuit Integrity Key (FIK) – a key that must be inserted to close the firing circuit to allow 300VDC to be sent to the firing contact on the gun.
Pre-arm/Arm/Safe – Button located on the LCS and RCS. When Pre-arm/Arm is selected, firing circuits are enabled.
Hold Fire – Button located on the LCS and RCS that will electrically prevent gun from firing while it is on.

Q

Close-In Weapon System (CIWS) Modes of Operation

A

Air Ready: Primarily a maintenance mode. Everything is on. Motors have power, transmitter radiates into a dummy load, and search antenna is spinning. It’s like having your car on, but sitting in park. Has the ability to accept remote designations from WCS through the RCS which modes mode to AAW Auto and mount will slew and attempt to find target that WCS sent. Can fire in PAC (Pre-aim calibration) which aligns the track antenna to the gun to make sure the mount shoots where it’s pointing.
AAW Manual: Mount is actively searching for threats. Mount will move on its own towards a threat, when something meets engagement criteria, but will not fire unless the operator pushes the fire button.
AAW Auto: Same as AAW Manual except mount will fire on its own.
Surface: Uses the Phalanx Thermal Imager (PTI) to search for surface targets (FAC/FIAC) and low slow flyers (Helicopters, UAV). Operator manually moves mount via Fixed Hand Controller on the LCS or RCS. Has the ability to video track a target or can be used in a point and shoot way as well.
Anti-UAV: A new mode in B217, combining aspects of AAW and Surface modes to better engage UAVs utilizing both the PTI and Track antenna. The operator selects a target on the PPI and the mount will move to track it, at which point it can be engaged using 1.2 or 2 sec bursts.

Q

Types of CIWS Rounds:

A

20MM Cartridge. Each projectile is encased in a colored Sabot (hard plastic covering). Projectiles are encased in the sabot to engage the barrel rifling. The projectile is smaller than the diameter of the barrel, due to the high rate of fire the gun produces we use a smaller round encased in plastic to extend barrel life.
DU- Depleted Uranium (Orange)
TN- Tungsten (White)
ELC- Enhanced Lethality Cartridge (Red)

We only carry the MK 244 Enhanced Lethality Cartridge onboard.

Q

CIWS Loading

A

20MM rounds are carried in links to assist in storage and to facilitate loading. A loader unit is mounted to the front of the drum and linked ammunition is fed into the unit. At the point the Gun/Ammunition Handling System (GAHS) is rotated as the loader pulls the 20MM round out of its link and inserts it into the system, while simultaneously inserting a dummy round into the empty link to be removed. Even when CIWS isn’t loaded, a minimum of 1400 rounds of dummy ammunition are kept loaded in the drum to act as a counterbalance.

TLAM Guidance Systems
1. DSMAC (Digital Scene Matching Area Correlation) 2. TERCOM (Terrain Contour Matching) 3. GPS (Global Positioning System) 4. INS (Inertial Navigation System)
87
DSMAC (Digital Scene Matching Area Correlation)
When a TLAM flies over a DSMAC scene (ground area from which imagery is obtained) a downward-looking electro-optical camera takes a series of snap shots. The TLAM then compares the snap shots to a reference map stored in the missile’s computer to determine the TLAM’s position. The reference map is part of the mission data that is loaded during missile spin up.
88
TERCOM (Terrain Contour Matching)
A system that compares radar altimeter-measured terrain heights beneath TLAM’s flight path with digitized terrain heights stored in the guidance computer to update the missile’s navigation.
89
GPS (Global Positioning System)
A satellite navigation system that aids in missile navigation.
90
INS (Inertial Navigation System)
By utilizing a combination of gyroscopes and accelerometers, INS provides continuous missile location data that the guidance computer uses to determine the heading, altitude, and speed required to fly the missile along its planned route. Prior to launch, the missile INS is aligned with ship’s INS (ship’s gyro). INS is not sufficient alone to guarantee the missile will hit its assigned target. The INS output to the guidance computer is updated from several navigation sources while the missile is in flight to its target. These sources include altimeters, GPS, DSMAC, Vertical Update Points (VUP), and TERCOM.
91
PLP (preferred launch position)
Area where ship plans to launch from
92
FPPWP (first pre-planned waypoint)
This is the waypoint closest to land
93
Waypoint
a change of course or turn the missile takes. An EM will plan up to 5 waypoints
94
Booster drop zone

95
MSP (Manual Strike Package)
Built from either a LSP or Indigo message by EMs.
96
ESP (Electronic Strike Package)
Strike package sent directly into TTWCS (by tasking authority). Does not require EMs to manually type in missions before planning.
97
LSP (Launch Sequencing Plan)
A paper message from radio informing the ship of missions to plan only. Used for pre-planning purposes. EM must manually input missions into TTWCS in order to start planning.
98
Indigo
A paper message from radio allowing the ship to power up missile and authorization to launch missile as tasked.
99
ESP-L
Equivalent to a LSP sent directly to TTWCS.
100
ESP-E
Equivalent to an Indigo sent directly to TTWCS.
101
ATDC (Advanced Tactical Display Center)

Maintains a clear long-range track database for EMs
103
TSN (Tomahawk Strike Network)
Used to communicate with the TLAM-E using IMMM’s.
104

110
CFF (Call for Fire)
A quick response mission built manually in the Tactical TOMAHAWK Weapon Control System (TTWCS) or received via Mission Distribution System (MDS) as a strike package in response to SHORT NOTICE TASKING.
111
Types of Redirection
Flex- Alternate targets, also known as MOM (Multiple Outcome Missions) already planned in the mission. Retarget- Provides a new target to the in-flight missile. Missile takes into consideration no fly areas. Missile can be retargeted multiple times. Aim point Update- Similar to a retarget but ignores no fly areas. Once an aim point update has been sent, the missile cannot be redirected to another target.
112
Communication paths for receiving MDUs
1. RNI (Remote Network Interface) – I.P. to I.P. MDU via the internet. 2. EHF (Extremely High Frequency) - MDU is sent from one platform to another via satellite. Also called EHF point-to-point. 3. STE (Secure Telephone Equipment) – MDU is sent over an encrypted phone line.
113
Types of Engagements
1. TOT (Time on Top/Target) - Engagement is planned around the missile hitting the target at a specific time. 2. TOA (Time of Arrival) - Engagement is planned so that the missile arrives at the FPPWP at a specific time. 3. TOL (Time of Launch) - Engagement is planned so that the missile launches at a specific time.
114

119
TTWCS and C & D Doctrine
TTWCS is an offensive weapon. If for any reason, the launchers need to be taken by another weapon system for defense of the ship (AWS or UWS), TTWCS will automatically lose control of the launchers until AWS or UWS relinquishes control.
